## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__buzzradr__get_source_health` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__buzzradr__get_source_health` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

## Only reads (4)

Looks things up and changes nothing. Claude Code: allow.

### `get_daily_digest`

- The name "get_daily_digest" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Return the top ~12 trending topics for a vertical as a daily briefing. Use this when the user asks "what is trending today", "what is the AI news today", or wants a quick roundup. Each topic includes a title, AI summary, why-it-matters reason, a one-line "why this one" judgement (aiWhy; absent when none was generated), composite ranking score, platforms, keywords, trusted-source count, and its top items. The score combines source, coverage, engagement and freshness signals; it is not 24-hour discussion heat. locale="zh" opts into Chinese summaries (default English). Read the full topic at https://buzzradr.com/ai/{topicId}.
```

### `get_source_health`

- The name "get_source_health" says "get": a word for reading.
- Tag private-data: The description's first sentence says "message": it reads messages.
- Tag untrusted-input: The description's first sentence says "message": it reads messages, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Report the ingestion sources behind a vertical and their health: status, last fetch time, accepted/filtered item counts, and any public message. Use this to check data freshness or which platforms feed the radar.
```

### `get_topic`

- The name "get_topic" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Fetch one trending topic by its topicId (as returned by get_daily_digest / list_trends). Use this to drill into a specific story. Returns "topic not found" if the id is unknown or the topic no longer clears the public quality gate. locale="zh" opts into Chinese summaries (default English). Topic page: https://buzzradr.com/ai/{topicId}.
```

### `list_trends`

- The name "list_trends" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search and list trending topics for a vertical with optional filters. Use this to answer "what is happening with <keyword>", to filter by platform, or to pull a ranked list. keywords/platforms narrow the results; sort="hot" (default) ranks by composite ranking score, sort="time" by recency; limit is 1-50 (default 20); locale="zh" opts into Chinese summaries (default English). Read a topic at https://buzzradr.com/ai/{topicId}.
```

## Claude Code permissions

      "mcp__buzzradr__get_source_health"
    ],
